Specialised cells
Muscle Cells Nerve Cells
Specialised to contract quickly to move bones Specialised to transmit electrical signals from one
place in the body to another
Protein filaments - in layers that slide over one Axon - is long so impulses can be carried along long
another to contract distances
Mitochondria - provides the energy for muscle Dendrites - extensions from main body means
contraction branched connections can form with other nerve
Can store Glycogen - which is used in respiration cells, can communicate with other nerve cells
by mitochondria Nerve endings - have many mitochondria which
supply energy to make neurotransmitters
(transmitter chemicals), allows impulses to be
carried from one cell to another
Root Hair Cells Sperm Cell
Specialised to take up water by osmosis and Specialised to carry DNA to the egg cell for
mineral ions by active transport from soil reproduction
Tail - to propel itself through water, to get to the egg
Mitochondria - lots to release the energy needed to
Root hairs - large surface area, more water uptake swim fast nd for long
Large permanent vacuole - maintains Streamline head - to move easily through liquids,
concentration gradient, more concentrated than less resistance
soil Enzymes in head - to allow it to penetrate the egg
Mitochondria - provide energy for active transport
